Dickinson has said Cosby drugged her in Lake Tahoe in 1982 and then when she was unconscious, penetrated her vaginally and anally. Janice took a pic of Cosby in a robe in the room where she claims the rape occurred.
The statute of limitations has long since run, but Dickinson says she has a fresh claim after Cosby's team released a statement saying she had fabricated the story.
So now Dickinson is suing Cosby for defamation and emotional distress. In the lawsuit, obtained by TMZ, she's asking for unspecified damages.
We reached out to Cosby's team ... so far no word back.
